Abu Hayyan’s father, Abu Salamah bin Abdur Rahman, says: Sayyiduna Abdullah bin Amr and Sayyiduna Abdullah bin Umar (may Allah be pleased with them) met each other, then Sayyiduna Abdullah bin Umar (may Allah be pleased with them) turned away and began to weep. The people asked: O Abu Abdur Rahman! Why are you weeping? He said: Because of what he has related to me. He says that the Messenger of Allah (peace and blessings be upon him) said: That person will not enter Paradise in whose heart there is even a mustard seed’s weight of arrogance.
